I want to prepare the soil for my new Miracle Fruit plant. Apparently they prefer pH 4.5. What are my options for creating this acidic environment?
I certainly want to do better than my last effort... I had two 2" Miracle Fruit plants growing in a big pot with my Blueberries for about 3 months, until they both suddenly crashed at the same time - turned brown and died. I'm not sure why. The Blueberries are still fine.
The only thing I did to prepare that soil was mix pine needles through it, and I added a tiny bit of apple cider vinegar to their water. They were fine on that until 3 weeks ago Any ideas?!
